%X 基于有向距离、行列式等理论，推导直线上、平面内、空间内三个恒等式的坐标表达式，从而使中学数学中几何内的求解和证明问题变成简捷、系统的代数问题，实例的应用展示所得结论的可靠性和实用价值。<br />
Based on the theory of directed distance and determinant, the coordinate expressions of three identities on a line, in a plane and in space are derived, thus, the problem of solving and proving in geometry in middle school mathematics becomes a simple and systematic algebra problem. The application of examples shows the reliability and practical value of the proposed conclusions.
